According to the comments, this is copper clad aluminum. Now I'm not saying there is something wrong with CCA for this application, but if somebody was already worried about cables and wanted copper, this is not the cable to buy.
Didn't look at that link, but if CCA then it seems the general advice is to adjust AWG by three (i.e. if you get cca 16g then an equivalent of 19g of all copper is generally considered equivalent....altho cca may simply be brittle, too)

He is keeping the cables and replacing the plugs. It makes me wonder does replacing these power chords with aftermarket snake oil rubbish void your warranty?

Ah, misread the comment.
But never mind that, does changing the connectors alter the custom quantum tunneling?
I've worked with CCA. It was just like copper mechanically. You wouldn't really know unless you look hard at the cut ends.

I don't really agree with this since what I posted was to do with an extremely serious safety issue more so than a snake oil one. This is why I posted it separately. I didn't want a safety issue buried amongst a tongue in cheek topic where some people who own this product won't read this thread simply because they don't know their cable is inherently unsafe. Oh well I hope no one gets killed by these cables.Just merged several new oily threads so if you are confused it may be intentional…

I'll pass this on if someone gets killed. Thanks for your concern. I wonder how Amir would react if he was testing one of these cables and came across this fault? I guess I'll never know since it's now buried.Audiophiles don't feel pain the way we do
He has found real problems before this. High end manufacturers seem to have little concern.
I wonder if oil of snakes has an actual aroma, because I'm sure you'd be able to smell that on these
Copper Oxide, the by-product of oxidation, is highly conductive and one of the reason why copper cabling is chosen for wire builds in many industries. The oxidation actually forms a barrier to prevent further oxidation even though the copper oxide is still highly conductive.
You get sulfides too; and in any event Amir has experienced poor connections causing very measurable distortion.
My first guess is @Amir was not testing pure copper, but then again I'm not an authority on the subject. I never drank the Kool-Aide when it came to hi-end cables and especially oxygen-free copper cables.
I pulled this from copper.org:
"A noble metal, copper gives your system unequaled reliability and longevity. The pure copper used in building wire is described by corrosion specialists as noble metal. This means it is not subject to galvanic corrosion when connected to other, less noble metals and alloys. Copper wiring will also resist corrosion from moisture, humidity, industrial pollution and other atmospheric influences – to insure safe, trouble-free performance for the life of your system."

The conditions for safe wiring of 100s of volts is a bit different than expecting less than 0.01% THD from a low voltage, low current connection.

That was a good read
I'm old enough, they still used those a little when I was young. Although selenium was getting popular.
